Hello @Bobby Visser ,
I understand you received an email regarding: "... convert classic admin roles that still need access to your subscription to Azure RBAC roles immediately." But you do not recognize the subscription id that was associated in the email.
I hope the suggestion is helpful to find the subscription id which was provided by Achraf Ben Alaya.
Additionally you can find the subscription id which was associated to the tenant using the azure portal.
login to portal.azure.com>Subscriptions>Overview and you can check the subscriptionID.
You are receiving this email because starting from April 30, 2025, any Co-Administrator or Service Administrator role assignments will lose access. Microsoft sends this email as a precautionary measure to help organizations avoid unexpected access issues.
I want you to confirm that it is an active subscription? If it is an active subscription and assigned any classic administrator roles then you need to convert these role assignments to Azure RBAC immediately.
Steps to Check in Azure Portal:
1.Navigate to Azure Portal → Subscriptions
2.Select your subscription → Go to Classic Administrators tab
3.If no users are listed, it confirms that your subscription has no classic administrator roles
4.If you manage multiple subscriptions, repeat the same steps for each.
If you see any Co-Administrator or Service Administrator role assignments for your subscription you need to convert these role assignments to Azure RBAC immediately.
Follow these steps to convert the Co-Administrator or Service Administrator role to the Owner role: Co-Administrator and Service Administrator Retirement Guide
